I think their point is that knowing there’s an air tag on something nearby indicates it’s probably something of value worth stealing.

How often is that something otherwise invisible, however? Like if I put one on my bike are there really many thieves who would otherwise not have considered it? I’m sure there are some small things which are relatively covert but it seems like a relatively uncommon situation.

Feel free to steal my daughter's water bottle. I don't track it because it's valuable, I track it because she's irresponsible.

Unlike my eyeballs that can see an expensive bike in the range of the airtag transmission.

Almost all of the tags are on people’s keys which hold close to no value
